Large-span three-arch three-cable-plane fully-combined structure system bridge and construction method thereof
The invention discloses a large-span three-arch three-cable-plane fully-combined structure system bridge and a construction method thereof.The bridge comprises three cable planes, each cable plane comprises three arch ribs fixedly connected with longitudinal beams through a fully-combined structure consolidation system, and bidirectional consolidation of the arch ribs and the beams is achieved; all consolidation branches of the first composite structure consolidation system and the second composite structure consolidation system are respectively consolidated with arch ribs, beams and piers through various consolidation modes and combinations of high-strength bolts, welding, built-in prestressed steel beams or cast-in-place concrete and the like, so that two-to-seven-direction multi-arch multi-cable-plane fully-consolidated bridges is realized; the safety and stability of the bridges are improved, the stress span, transverse internal force and mid-span deflection of the cross beams arereduced, the stress state of the longitudinal beams and a bridge deck system is improved, meanwhile, construction is easy, and the appearance is attractive.
本发明公开了大跨度三拱三索面全组合结构体系桥梁及其建造方法，所述桥梁包括三个索面，每个索面包括三个经全组合结构固结体系与纵梁固结相连的拱肋，实现了拱肋与梁的双向固结；第一组合结构固结体系和第二组合结构固结体系的所有固结分支经高强螺栓、焊接、内置预应力钢束或现浇混凝土等多种固结方式及其结合分别与拱肋、梁、墩进行固结，从而实现二至七向多拱多索面全固结的桥梁，提高了桥梁的安全性和稳定性，降低了横梁受力跨径、横向内力及跨中挠度，改善了纵梁和桥面系的受力状态，同时施工简单，外形美观。
